ANTON FREDERIKSEN, OF COPENHAGEN, DENMARK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 745,175, dated November 24, 1903.

Application filed August 8, 1903.

T0 aZZ whom it may concern.-

Be it known that I, ANTON FREDERIKSEN, a subject of the King of Denmark, residing at Oopenhagen,Denmark, have invented certain new and useful Improvements in Bottle-Stop pers, of which the following is a specification.

This invention relates more particularly to bottle-stoppers which may be securely locked in closing position and is illustrated in the accompanying drawings, in which Figure 1 is a sectional view of the upper part of a bottleneck embodying a part of this invention. Fig. 2 is a top plan view of the same. Figs. 3, 4, and 5 are views showing the stopper. Fig. 6 is a view showing the stopper inserted in the bottle.

At the top of the bottle-neck a are two inwardly-projecting lugs 19 c. The upper inner portion of the neck is preferably somewhat tapering and terminates in an inwardly-projecting beveled shoulder d.

The stopper c is provided with an upper corrugated flange f, by means of which the stopper is inserted and removed. The lower end of the stopper is provided with a knob 2', which holds a yielding closure-ring j, the latter being adapted to engage with the beveled shoulder d in the bottle-neck. On either side of the stopper e are cam-like projections, between which are slots 9 h.

The operation of the stopper is readily understood from the description and drawings. The stopper is grasped by the top or flange f and inserted in'the neck of the bottle, with the slots g h registering with the lugs 17 c. Vhen the stopper has been pressed down against the shoulder (Z, so that the yielding Serial No. 168.755. (No model.)

closure j is pressed tightly against the same, it is turned so that the upper faces of the camstrips are brought under the lugs Z) c, and a further revolution of the stopper causes it to be pressed downward by the cams and securely locked in position. lVhen it is desired to remove the stopper, it is again turnediso that the slots and lugs register and is readily removed. The stopper may be sealed, if desired, by means of a seal is, which engages the same and the neck of the bottle, as shown in Fig. 6. v

Having thus described'my invention, which I do not wish to limit to the particular form shown or to any particular material, what I claim, and desire to secure by Letters Patent,

In a bottle-stopper, the combination with the bottle-neck provided with an upper internal conical portion terminating in a bev-' ANTON FREDERIKSEN. I
